Important user information
This manual explains how to install, operate and configure a SL-MOD-GW. This device may only be used for
the applications described in this document.
This manual is to be used with a SL-MOD-GW with firmware version 1.6.
These instructions are intended for use by trained specialists in electrical installation and control and automation
engineering, who are familiar with the applicable national standards and safety procedures.
Safety Precautions
ELECTRICAL HAZARD
• This equipment must be installed and serviced only by qualified personnel. Such work
should be performed only after reading this entire set of instructions.
• Before performing visual inspections, tests, or maintenance on this equipment, disconnect
all sources of electric power. Assume that all circuits are live until they have been completely
de-energized, tested, and tagged. Pay particular attention to the design of the power
system. Consider all sources of power, including the possibility of backfeeding.
• Apply appropriate personal protective equipment and follow safe electrical practices.
• Turn off all power supplying the equipment in which the SL-MOD-GW is to be installed
before installing, wiring or removing the SL-MOD-GW.
• Always use a properly rated voltage sensing device to confirm that power is off.
• The successful operation of this equipment depends upon proper handling, installation, and
operation. Neglecting fundamental installation requirements may lead to personal injury as
well as damage to electrical equipment or other property.
Failure to follow these instructions could result in death or serious injury!

1.Introduction
The SL-MOD-GW is a Modbus/TCP to Modbus RTU gateway.
The gateway features one serial port which can be configured as either RS-232, RS-485 or RS-422 and an
Ethernet port. It can be mounted on a DIN rail.
Usage and configuration of the gateway is simple and conveniently performed using a web browser which
connects to the embedded web server.
Possible areas of application are:
• PLC connection
• Operator panel interfacing
• HMIs
• SCADA integration
• Remote control & monitoring
• Data logging

1.1 Features
The SL-MOD-GW gateway provides the following key features:
• Modbus/TCP protocol (Ethernet)
• Modbus RTU protocol (either RS-232, RS-485 or RS-422, software configurable)
• Embedded web server for easy configuration and commissioning using a web browser
• Firmware upgradeable via Ethernet
• DIN rail mountable
• 24 V DC (10-30 V) power supply
• Status LEDs for power, Ethernet link, device status and communication status
1.2 Quick start checklist
• Read this set of instructions properly and in its entirety.
• Mount the unit.
• Connect the power. Do not connect yet serial ports.
• Configure the Ethernet communications settings with a web browser (using an Ethernet crossover cable) or
with a terminal program like HyperTerminal (using a null modem cable)
• Configure the serial line communication settings.
• Configure the operational aspects of the device.
• Wire serial line interfaces.

2.1 LED indicators
Four LEDs located at the front panel indicate the status of the device. The LEDs assist maintenance personnel
in quickly identifying wiring or communication errors.
A LED test is exercised at power-up, cycling each LED off, green and then red for approximately 0.25 seconds.
At the same time the power-on self test of the device is performed.
4UMSLMODGW-1006
The following table outlines the indicator condition and the corresponding status after the power-on self test
has been completed:
LED Function Condition Indication
Off No power applied to the device.
Power Power Green Power supply OK
Off No Ethernet link
Link Ethernet link Green Ethernet link OK
Off The device has an unrecoverable fault; may need replacing.
Flashing green
1 s rate
Device operational but needs commissioning due to configu-
ration missing, incomplete or incorrect.
Green The device is operating in normal condition.
Flashing red
1 s rate
Device operational but has a fault listed which requires ac-
knowledgment.
Status1 Device sta-
tus
Red
The device has an unrecoverable fault; may need replacing.
Flashing sequence and rate of Status2 LED indicates fault
class.
Off No Modbus/TCP connection.
Status2 Communica-
tion status Green Modbus/TCP connection established.
